| 摘要: |
| 提出了一种专门针对建筑物图像的线条风格化自动生成算法,该方法首先利用快速的带有误判控制的图像线段检测算法得到建筑物的外轮廓和门窗的线条特征,通过该特征增强边切向流中直线的权重,然后在此基础上利用基于流的高斯差分得到建筑物的线条画,充分展现了建筑物的线条轮廓.该方法简单、可靠,而且容易实现,实验结果充分证明了该方法的有效性. |

| Abstract: |
| This paper presents an automatic line-drawing method designed for building images. The fast line segment detector with a false detection control and detects the outline and the door, or window edge features detected, which are used in the construction of edge tangent flow. Based on the modified ETF, the Difference-of-Gaussians is used to render the final line drawing styles. This scheme gives clear line features for building images without much noise, which is also simple and easy to implement. The test results verify the effectiveness of the presented algorithm. |
